Description

  The present invention relates to a locking module having the characteristics of the universal component according to claim 1 of, for example, published patent application DE 195 24 568 A1, and its assembly procedure. The lock module is generally attached to the automobile door, specifically to the side door of the automobile.

  The published patent application DE 195 24 568 A1 discloses a motor vehicle door lock called a lock module, the motor vehicle door lock comprising a locking element, a locking lever system, and an actuating lever system acting on the locking element. , Including an external handle. The locking element has a lock mechanism including a rotary latch and a claw portion. The lock mechanism is a part of an automobile lock.

  The automotive latch rotary latch includes a fork-type intake slot that receives a clamping bolt for the vehicle door or lift gate when the vehicle door or lift gate is closed. The clamping bolt then rotates the rotary latch from the open position to the closed position. When the rotary latch reaches the closed position, the clamping bolt can no longer exit the rotary latch take-in slot. In the closed position, the pawl locks the rotary latch, making it impossible for the rotary latch to reversely rotate and return to the open position.

  Apart from movable parts such as the rotary latch and the pawl, the car lock also includes parts that are not movable once installed. These generally include a frame plate made of metal, and the rotary latch and the claw portion are rotatably installed on the frame plate. The lock also includes a plastic housing that can be closed by a cover plate.

  Automobile locks have a closed position (i.e. so-called preliminary gripping position and main gripping position) that is subsequently taken by a rotary latch while locked. In order to improve the comfort level, it is possible to provide a drive, in particular an electric drive, which is connected to the rotary latch when the rotary latch reaches the preliminary gripping position. Move to gripping position. Such a drive device is disclosed in German patent application 10 2009 026 921 before publication of the application. A lock having such a driving device is called a servo lock.

  The features described above can be a separate part of the invention or a combined part.

The pre-published German patent application DE 2010 003 409 describes that the amount of assembly work associated with the mounting of modules on the vehicle door has increased year by year, especially in the case of the mounting of automobile side doors. The attached module can be a power window, a car door lock, a loudspeaker, and a drive for a locking / unlocking mechanism. The cause of the increased assembly work is that the space is more constrained by the increase in the number of parts of the module and the number of other parts such as side impact protection materials. In addition, the presence of many different types of vehicle door types further increases assembly requirements.

  In view of the above, the present invention provides a lock module that contributes to a reduction in required assembly work.

  In order to solve this problem, the lock module has the features described in claim 1. Advantageous embodiments are described in the dependent claims.

The locking module has a plurality of parts, ie at least two parts selected from:
A lock having a lock mechanism comprising a claw part and a rotary latch, specifically a servo lock. A drive device for the lock, particularly preferably a servo lock, specifically an electric drive device.・ Operating lever system ・ Locking lever system ・ Opening handle, specifically handle module with outer opening handle

  The lock module includes at least one drive unit that is movably installed. Thus, the drive device is rotatable relative to one or more other parts of the lock module.

  The aforementioned parts already feature as movable elements in prior art embodiments. The lock includes a plurality of movable elements, such as a rotary latch, one or more pawls that secure the rotary latch in a preliminary or primary gripping position, and one pawl that holds the rotary latch It includes one or several anti-rotation levers that lock the claw when locking. The open handle is movably mounted on at least one further part of the handle module. The lock module can be operated by a movable fixed part of the individual elements of the part. The locking mechanism requires a moving part that allows the door to be closed. The door is opened by the mobility of the handle.

  In contrast, the movable installation of the drive device relates to a movable connection that does not move during normal operation once installed. In a preferred embodiment, the movable connection does not move when the drive is installed, since the drive is fixed during installation and can no longer be moved. Thus, the mobility is applied only when the lock module is not attached to the door.

  The movable installation part can solve the problem of installation. The actual mounting can be promoted by utilizing the mobility. The drive device is connected to one or more parts of the lock module at the start of assembly as compared to the spatial position or arrangement occupied when attached to the one or more parts of the lock module. It occupies another spatial position or arrangement. The lock module can be applied to different mounting conditions using the movable installation part. In the first door type, the drive occupies a different position or arrangement relative to one or more parts of the lock module as compared to being attached to another type of door.

  Specifically, the lock driving device is movably connected to the lock, and is preferably movably connected to the housing, and more preferably movably connected to the cover plate of the lock. Therefore, a desired movable installation part can be easily achieved by such a design. Particularly preferred is that the drive device is physically separated from the lock by a web connection.

  The movable connection can be a flange connection or a connection including it. The drive device is provided with a flange. Thus, the desired connection can be achieved in an easy technical manner.

  Preferably, the movable connection is lockable and / or includes a snap-on element for locking the connection. This further facilitates assembly. In this way, the locking module can be supplied for pre-assembly into the door by the supplier so that the drive is already in a position where installation is facilitated at the start of assembly. The original position is reliably maintained from the beginning by the fixing part and / or the latch element. By releasing the fixation, the position of the driving device can be changed to facilitate the completion of the assembly. The latch element or the resulting snap connection is preferably designed such that the applied force is sufficient to cause the drive arrangement to change relative to other parts in the desired manner.

  In one embodiment, the locking and / or latching elements are designed such that the drive can only be fixed and / or snapped in a predetermined arrangement. This prevents an incorrect intermediate position and / or placement of the drive device relative to other parts of the lock module that prevent installation.

  In one embodiment, the drive is connected to the lock by a flexible Bowden cable to move or actuate the locking element. The Bowden cable is a typical element of such a drive, in particular when these parts are arranged separately from one another. Therefore, the drive part is particularly suitable for a movable fixed part, which makes it very easy to mount.

  The drive unit functions to move the rotary latch from a preliminary gripping position to a primary gripping position, thereby increasing comfort when the door is closed.

  The drive unit is preferably an electric drive device, preferably an electric motor or a shape memory alloy, that is, an alloy capable of rapidly changing its shape when a temperature change occurs.

  In one embodiment, the lock includes a first pawl that engages the rotary latch in a preliminary gripping position and a second pawl that engages the rotary latch in a primary gripping position. On the other hand, a single pawl can be sufficient to engage the rotary latch in the preliminary gripping position and the primary gripping position.

  In one embodiment, the lock includes an anti-rotation lever capable of fixing the claw portion at the engagement position.

  In one embodiment, an automatically opening locking mechanism having the anti-rotation lever is provided. That is, when the locked state by the rotation preventing lever is released, the lock mechanism can be automatically unlocked.

  In the following, the present invention will be described in detail with reference to the figure showing a locking module.

FIG. 1 shows a lock module having a servo lock 1, an electric drive 2 for the lock 1, and a handle module 3 comprising a handle back plate 3a and a handle 3b.

  FIG. 1 shows a lock module having a servo lock 1, an electric drive 2 for the lock 1, and a handle module 3 comprising a handle back plate 3a and a handle 3b. The driving device 2 is movably connected to the servo lock 1 by a web 4. The servo lock includes a frame plate 1a, a lock housing 1b, and a cover plate 1c. The rotary connection between the servo lock 1 and the electric drive 2 includes snap-type means, which allow snap-type connection at at least two different snap positions. In general, only two different snap positions are sufficient for significant simplification of installation. Therefore, it is further preferred to have only two different fixed positions or snap positions so that only two different fixed positions and / or snap positions for the servo lock 1 of the drive device 2 are possible. By doing so, normal operation failures are reduced. Since the number of the snap positions or the fixed positions is limited, it becomes impossible for the driving device to be snap-connected or fixed at an arbitrary position. This also makes it impossible for the drive to be snapped or fixed in a position which is not preferred.

  Using the Bowden cable 5, the lock 1 arranged away from the drive device 2 can move the rotary latch of the lock 1 from its preliminary gripping position to its main gripping position. Due to this spaced arrangement, the drive device can be arranged on a part of the door unless otherwise required. Although the drive 1 and the lock 2 are separated by the web connection 4, it is possible to provide an assembled lock module for the final installation of the door.

  Alternatively or additionally, the handle module 3 can also have a rotary connection to the lock 1, for example to facilitate attachment. However, it has been found that it is particularly important to provide the drive device 2 with a rotary connection, since the handle 3 and the lock 1 must always be arranged in a specific position relative to the door. . Meanwhile, the actual position of the driving device can be selected or specified flexibly. Therefore, a significant advantage is achieved only when utilizing this fact and utilizing the movably fixed drive device 2. In general, this is sufficient with a rotary fixing operated with a flexible Bowden cable. However, if necessary, it is possible to use different movable fixed parts. Each fixing part can, for example, slide or further fold, as another method, or three-dimensionally move the drive in addition to the rotational movement. Therefore, for the reasons described above, when an accurate position between the handle and the lock is normally required, the handle 3 may be firmly connected to the lock 1 by the web 6, for example. preferable.
